Abstract
The invention discloses a kind of shale oil-sludge treatment with medicament, this medicament comprises following component and weight percent: phenolic group Soxylat A 25-7 50-60%, fatty alcohol-polyoxyethylene ether 15-20%, high fatty acid sodium 5-10%, sodium carbonate 10-30%.Medicament of the present invention belongs to the tensio-active agent of mixed type, be configured mainly for shale greasy filth, reach real efficient, environmental protection, whole treating processes can be carried out in the reactor closed, and reaction is carried out at ambient pressure, and condition is simple, do not need high temperature, high pressure, there is not the discharges such as poisonous fume, safe and reliable, can not secondary pollution be produced.
Description
One, technical field
The invention belongs to treatment agent technical field, be specifically related to a kind of shale oil-sludge treatment with medicament.
Two, background technology
Shale greasy filth is a kind of solid waste that destructive distillation enterprise generates in process of production, and its main component is shale crude oil, sewage and solid residue.The method that current process industrial greasy filth generally adopts has: burning method, Thermal desorption method, solvent extration, biological treatment, chemical WATER-WASHING METHOD etc.The power consumption of these treatment process ubiquities is large, construction investment large, complex process, easily form secondary pollution problems.
Three, summary of the invention
The object of this invention is to provide a kind of shale oil-sludge treatment with medicament, adopting this medicament to process the weak point that effectively can overcome existing treatment process for carrying out shale greasy filth.
For achieving the above object, the technical solution used in the present invention is: this medicament comprises following component and weight percent: phenolic group Soxylat A 25-7 50-60%, fatty alcohol-polyoxyethylene ether 15-20%, high fatty acid sodium 5-10%, sodium carbonate 10-30%.
This medicament using method is:
first with water, medicament is diluted to the solution that mass concentration is 0.3%-0.5%, then this solution is mixed in a reservoir with the mass ratio of shale greasy filth according to 1:1;
heating container to 60 DEG C, stops heating after stirring 2 hours, stirs with the rotating speed of 80-100 rev/min;
leave standstill after 3 hours, in shale greasy filth, oil phase, aqueous phase, residue are obviously divided into upper, middle and lower-ranking.
Medicament of the present invention belongs to the tensio-active agent of mixed type, be configured mainly for shale greasy filth, reach real efficient, environmental protection, whole treating processes can be carried out in the reactor closed, and reaction is carried out at ambient pressure, and condition is simple, do not need high temperature, high pressure, there is not the discharges such as poisonous fume, safe and reliable, can not secondary pollution be produced.After this chemicals treatment, the shale crude oil in shale greasy filth, sewage, residue can fully be separated, and can reclaim the shale oil of more than 98%.The shale oil wherein extracted can directly be sold as finished product shale oil; Sewage can recycle and outwards not discharge; The residue produced can baking bricks, manufacture the directions such as carbon black and apply, also can add gas retort carry out destructive distillation again reclaim the shale oil that remains.
Four, embodiment
Embodiment 1: phenolic group Soxylat A 25-7 57%, fatty alcohol-polyoxyethylene ether 16%, high fatty acid sodium 6%, sodium carbonate 21%.
Embodiment 2: phenolic group Soxylat A 25-7 55%, fatty alcohol-polyoxyethylene ether 20%, high fatty acid sodium 8%, sodium carbonate 17%
Experimental example: the greasy filth selecting Fushun Mining Ind Group Co., Ltd.'s shale oil refinery destructive distillation to produce is tested, and experimentation is as follows:
1. the medicament service water configured is diluted to the solution that mass concentration is 0.5%;
2. determine that balance takes a certain amount of greasy filth after clean, be placed in beaker;
3. this liquid medicine and greasy filth are mixed in same beaker according to mass ratio 1:1, and put
In thermostat water bath, temperature is set as 60 DEG C;
4. open water bath with thermostatic control equipment, beaker is heated;
5. after the temperature that thermometer displayed value reaches test needs mensuration, with constant speed
80-100 rev/min of kind stirs, and opens timing register simultaneously, stops heating, stirs after 2 hours;
6. leave standstill after 3 hours, in greasy filth oil phase, aqueous phase, residue be obviously divided into upper, middle and lower, three layers.
Main result is as follows:
| Initial greasy filth oil length | Residue oil length after process | Shale oil recovery rate in greasy filth | Reclaim shale oil foreign matter content | |
| Example 1 | 49.20% | 1.06% | 99.42% | 0.06% |
| Example 2 | 49.20% | 1.30% | 99.32% | 0.04% |
According to above-mentioned testing sequence, service water used for dilution medicament is changed into the sewage produced in process shale greasy filth process, that is: the sewage between oil phase and residue, other conditions are constant, obtain following result:
| Initial greasy filth oil length | Residue oil length after process | Shale oil recovery rate in greasy filth | Reclaim shale oil foreign matter content | |
| Example 1 | 49.20% | 1.00% | 99.56% | 0.09% |
| Example 2 | 49.20% | 1.27% | 99.41% | 0.07% |
Can find out that medicament of the present invention has unusual effect for process shale greasy filth by experimental example above, fully can reclaim shale oil contained in shale greasy filth, required processing condition simply, easily operate.Meanwhile, sewage can use as recirculated water, can reduce the usage quantity of outer water displacement and water purification like this.
